2002 Jeep GC Limited Electrical Issues

I accidentally left the sunroof open on the Jeep the other night, and it happened to storm that night. There was a lot of water that got in the Jeep, but now there is no electrical activity. When the key is turned, there is no activity at all. I looked on here and tried to disconnect and reconnect the battery, but that was unsuccessful. I realize there are a lot of different electrical issues on this forum, but if anyone has any insight that would be great. Thanks.
